[Hepatic metastases of breast cancer. Analysis of the parameters which influence the response to chemotherapy].

In a serie of 759 patients treated for metastasized cancer of the breast, presence of an hepatic focus was observed in 29 percent of cases. Isolated hepatic metastases were found in 4 percent of cases while in 25 percent they were associated with other tissues. At the time of initial clinical staging, the difference between the hepatic metastases group and the other group stems from the much greater frequency of severity indices in the former group indicating a general and biological transformation of the metastatic tumor(s). At therapeutic staging, the slight effectiveness of medical therapies can be accounted for by the slight tolerance among patients with a secondary hepatic tumor(s). Lastly, it is interesting to note that progesterone receptor presence does not modify the prognosis in hepatic metastases cases.
